Answer:
The circumference of the circle is 75.36cm
Step-by-step explanation:
There are two ways you can solve this, one is by using the radius and multiplying it by 2 and then pi which is 3.14, and the other is to use the diameter which is the radius times 2, and the thingy gave you the diameter, and you multiply it by 3.14 which is pi
5x−4y=−10
y=2x−5
x=x=x, equals
y=y=y, equals
Answer:
✎ ANSWER:-[tex]y = 2x - 5[/tex]
Substitute the value of y as 2x - 5 in the equation.
[tex]5x - 4y = - 10 \\ 5x - 4(2x - 5) = - 10 \\ 5x - 8x + 20 = - 10 \\ 5x - 8x = - 10 - 20 \\ - 3x = - 30 \\ x = \frac{ - 30}{ - 3} \\ x = 10[/tex]
Now, find the value of y
[tex]y = 2x - 5 \\ y = 2(10) - 5 \\ y = 20 - 5 \\ y = 15[/tex]
⎇ x = x = x, equals 10
⎇ y = y = y, equals 15
Answer:
if y = 2x-5
then in the second equation we can find the value of x
5x-4(2x-5) = -10
5x-8x+20 = -10
-3x = -30
x = 10
then the value of y = 20-5 = 15
therefore the value of x = 10 and y =15 (ans)

Find the distance d. Round your answer to the nearest tenth. Show all your work. Thanksss!
Answer: the distance for d is about 5.8 units
Step-by-step explanation:
Use the pythagorean theorem. a^2 + b^2+= c^2 . in this case, c^2 is the distance for d.
5^2 + 3^2= d^2
25+9= d^2
34= d^2
square both sides and d is approximately 5.818
Find the value of x and y
Answer:
2x + 20 = 3x-10
2x -3x = -20-10
-x = -30
x= 30
Checking part:
2x+20 = 2(30) +20 = 60+20 = 80
3x-10 = 3(30) - 10 = 90-10 = 80
Hence, the final answer is x = 30.
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
the angle should be the same so,
2x+20=3x-10
x=30

A student was asked to identify the following numbers as rational or irrational. Determine if the student has made any mistakes. Choose ALL the INCORRECT answers. There may be more than one answer
Answer:
Yes they are wrong, rational & irrational ones down below.
Step-by-step explanation:
So, lets start this by asking, what is a rational and irrational number?
Rational numbers are literally any numbers that arent pi, e, or other symbols, as well as square roots.
Irrational numbers are exactly the opposite, being the numbers that are symbols, including square roots.
Note that the symbols listed above such as pi are values that are neverending.
Now, using what we know of rational and irrational numbers, let see which answers are rational and which are not.
So, we start off with:
-13/3
I do not see a square root.
I do not see a symbol such as pi either.
It is not a ever going number.(number that continues infinitly)
So -13/3 is a rational number.
Next we have [tex]\sqrt{37}[/tex]
immediatly we tell it has a square root.
So [tex]\sqrt{37}[/tex] is a irrational number.
Next we have 0.1234
This is not a every going number.
There isnt a square root.
And it isnt a symbol.
So 0.1234 is a rational number.
Next we have [tex]-\sqrt{100}[/tex]
Again, we can immediatly know it has a square root.
So [tex]-\sqrt{100}[/tex] is a irrational number.
Next we have -77
This is not every going.
It doesnt have a square root.
It doesnt have a symbol.
So -77 is a rational number.
Lastly we have [tex]-\sqrt{12}[/tex]
Like the other ones, we can imediatly tell it has a square root.
So [tex]-\sqrt{12}[/tex] is a irrational number.
Bascially, to answer further questions, here is the criteria for a number being rational:
It does not have a square root.It does not have a symbol.It is not a infinitly going on number.If one of these criterias are not met, then you know its a irrational number.
Hope this helps! :D

Two phone companies one is 11/+.16/ min And another is 20+.11/min How many minutes will make both equal amounts
Answer:
Company one charges $11 + $0.16 per min.
Then if you talk for x minutes, the cost will be:
C₁(x) = $11 + ($0.16 per min)*x
For company two, the prize is $20 + $0.11 per min, and if yo talk for x minutes, the cost will be:
C₂(x) = $20 + ($0.11 per min)*x
Now we want to find the value of x, the number of minutes, such that the cost is the same with both companies.
C₁(x) = C₂(x)
$11 + ($0.16 per min)*x = $20 + ($0.11 per min)*x
($0.16 per min)*x - ($0.11 per min)*x = $20 - $11
($0.05 per min)*x = $9
x = $9/($0.05 per min) = 180 mins
If you speak for 180 minutes, the cost is the same in both companies.
If the measurement of angle 2 is 120 degrees, what is the measurement of angle 7?
Answer:
The measure of angle 7 is twice the measure of angle 2, then the measure of angle 7 is
angles 2 and 7 equal 180 degrees. 180 = 2x + x
180 = 3x
x = 60
angle 7 is twice x
angle 7 = 120

A student has taken three math tests so far this semester. His scores for the first three tests were 71, 75, and 79. Part A: Suppose his test scores continue to improve at the same rate. What will be the grade on the sixth and (final) test?
Answer:
The grade of this sixth and (final) test would be 91.
Step-by-step explanation:
This is an arithmetic series since each time the data is increasing by the common difference of 4, and we already know a₁ which is the first term in the sequence is 71, therefore we can say:
a₁ = 71
r = 4
a₆ = the sixth term that needs to be found out
n = 6
Formula of an arithemetic series:
aₙ = a₁ + r(n - 1)
a₆ = 71 + 4(6 - 1)
a₆ = 71 + 4(5)
a₆ = 71 + 20
a₆ = 91
Hence, the grade of this sixth and (final) test would be 91.
Hope this helps!

23. 5 milligrams
Step-by-step explanation:
Answer:
16. r = 20
t = 48
17. a = 104
b = 175
19. [tex]\frac{144}{20} =\frac{252}{35}[/tex]
7.2 = 7.2
20. [tex]\frac{27}{18}= \frac{21}{14}[/tex]

219 grams of peanuts
23. [tex]\frac{y}{2}: \frac{200}{80}[/tex]
50 milligrams of medication
Step-by-step explanation:
16. [tex]\frac{r}{32} =\frac{5}{8} =\frac{30}{t}[/tex]
8 · 4 = 32
5 · 4 = 20
r = 20
5 · 6 = 30
8 · 6 = 48
t = 48
17. [tex]\frac{52}{a} =\frac{10}{20} =\frac{b}{350}[/tex]
Here is a different method.
[tex]\frac{10}{20} =\frac{1}{2}[/tex]
52 · 2 = 104
a = 104
350 ÷ 2 = 175
b = 175
22.
[tex]\frac{8}{3} :\frac{584}{y}[/tex]
8 · y = 3 · 584
8y = 1752
8y ÷ 8 = 1752 ÷ 8
y = 219
23.
[tex]\frac{y}{2}: \frac{200}{80}[/tex]
y · 80 = 200 · 20
80y = 4000
80y ÷ 80 = 4000 ÷ 80
y = 50

When a graph is symmetric about the origin, it is an function.
When a graph is symmetric about the y-axis, it is an function.
A function is considered if f(-x) =
f(x), and it is considered
=
if f(-x) = -f(x).
Answer:
odd; even; even; odd
Step-by-step explanation:
The answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We know when the graph is symmetric about the origin it is an off function.
When the graph is symmetric about the y axis it is an even function.
When f(-x) = f(x) it is an even function
When f(-x) = -f(x) it is an odd function.
Thus, the answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.
